Modal Argument: The Mind is Not the Brain

[Brakeman]

Take the first point:

1. Knowledge comes from experience and reasoning. Exceptions are not considered true knowledge.

-In order for (1) to be true, it must thus be derived from experience and/or reasoning.
-However, the definition of knowledge (including "true knowledge") is not arrived at by experience or by reasoning. Therefore, according to logical positivism, it's own definition of knowledge is meaningless.
-Thus logical positivism, as your research has defined it, is self-refuting.

That is a non-sequitur. It does not follow from the definition of knowledge.

Your claim that "the definition of knowledge (including "true knowledge") is not arrived at by experience or by reasoning" is the polar opposite of the definition of knowledge.

I think you didn't make yourself clear enough for me. Can you spell it out in simple layman's terms? Some examples of it's self refutation would be nice.
